Book excerpt: Our world is made of rock. Although much of the Earth's surface is covered by vegetation, concrete, or water, if one digs down far enough solid rock will always be found. Those who live in a landscape where rock outcrops are obvious will have wondered about the kind of rocks they are looking at and how they came to be where they are now. This introductory book explains in simple terms what geology can tell us about the world. Many objects of great beauty which excite our curiosity, such as crystals or fossils, are to be found by examining rocks. Those searching for and examining such objects gain much more by knowing how and when they originated. In particular, fossils-while interesting in themselves-demonstrate to us from their context in geological time, the biological evolution, and these clues give an insight into the origins of life on earth. This copiously illustrated book includes a glossary of terms.
